Standard way of returning backbone collection in requirejs

[hostgatorboy]

I've seen different examples in different articles about how to return a Backbone collection (or View, for that matter) from a RequireJS define. For example:\[code\]define(['models/person'], function( person ) { var personCollection = Backbone.Collection.extend({ model: person, url: "api/person" }); // do this? return new personCollection(); // or this? //return personCollection();});\[/code\]Is there a memory advantage to either approach? Is there standard design pattern that dictates which should be used?The same question would apply to views, as I've seen them done both ways too.
